And to all of those "aviators" who are crying for implementing a SOP now so to avoid that someone steps out of the door, without having steps.
Yes, a much better idea is to leave everyone to their fate and watch the bodies pile up.
SOP on Big Airways. No door shall be opened or closed without an appropriate stand/steps in place.
If the caterers or steps move away and leave the door open. Get them back, then shut the door.
Do not open the door until the steps/caterers etc are in position.
By the way that little strap that so many feel is a safe way of protecting personel from the open doorway is about as much use as a chocolate fireguard.
